Updates qs from 6.13.0 to 6.16.0

Changelog

Sourced from qs's changelog.

6.16.0

  • [New] stringify: add a depth option to bound recursion depth (default Infinity)
  • [Fix] stringify: serialize Date values when a filter is provided
  • [Fix] parse: enforce arrayLimit on comma groups under []= when throwOnLimitExceeded is set
  • [Fix] parse: flatten a collection appended to an overflowed array (#571)
  • [Fix] utils: isBuffer: do not invoke a non-callable constructor.isBuffer
  • [Fix] stringify: do not let allowEmptyArrays skip cycle detection (or drop own keys) on an empty array with own properties
  • [Fix] stringify: encode dots in a top-level key with a primitive value when encodeDotInKeys is set (#562)
  • [Docs] threat model: clarify stringify deep-nesting DoS is caller-bounded
  • [Docs] clarify arrayLimit is a representation threshold, not an element-count cap
  • [Tests] parse: remove a test that pinned []= comma groups escaping arrayLimit
  • [Tests] stringify: pin current encodeDotInKeys separator-dot behavior
  • [Dev Deps] update @ljharb/eslint-config, eslint
  • [Dev Deps] update eslint, evalmd

6.15.3

  • [Fix] parse: enforce throwOnLimitExceeded for cumulative array growth via combine/merge
  • [Fix] utils: respect encoding of surrogate pairs across chunks (#559)
  • [Robustness] parse: throw the arrayLimit error before splitting oversized comma values
  • [Robustness] utils.merge / utils.assign: avoid invoking __proto__ setter when copying own properties
  • [Robustness] utils: enforce arrayLimit consistently across merge's array paths
  • [Perf] utils: make compact O(n) via a side-channel visited-set instead of Array.indexOf
  • [Deps] update side-channel
  • [Dev Deps] update eslint, mock-property, tape
  • [Tests] parse: characterize current lenient handling of unbalanced bracket keys (#558)

6.15.2

  • [Fix] stringify: skip null/undefined entries in arrayFormat: 'comma' + encodeValuesOnly instead of crashing in encoder
  • [Fix] stringify: use configured delimiter after charsetSentinel (#555)
  • [Fix] stringify: apply formatter to encoded key under strictNullHandling (#554)
  • [Fix] stringify: skip null/undefined filter-array entries instead of crashing in encoder (#551)
  • [Fix] parse: handle nested bracket groups and add regression tests (#530); changes output for some unbalanced bracket keys (see #558)
  • [readme] fix grammar (#550)
  • [Dev Deps] update @ljharb/eslint-config
  • [Tests] add regression tests for keys containing percent-encoded bracket text

6.15.1

  • [Fix] parse: parameterLimit: Infinity with throwOnLimitExceeded: true silently drops all parameters
  • [Deps] update @ljharb/eslint-config
  • [Dev Deps] update @ljharb/eslint-config, iconv-lite
  • [Tests] increase coverage

6.15.0

  • [New] parse: add strictMerge option to wrap object/primitive conflicts in an array (#425, #122)
  • [Fix] duplicates option should not apply to bracket notation keys (#514)

6.14.2

  • [Fix] parse: mark overflow objects for indexed notation exceeding arrayLimit (#546)
  • [Fix] arrayLimit means max count, not max index, in combine/merge/parseArrayValue
  • [Fix] parse: throw on arrayLimit exceeded with indexed notation when throwOnLimitExceeded is true (#529)

Updates express from 4.21.2 to 4.22.3

Release notes

Sourced from express's releases.

v4.22.2

What's Changed

  • fix: restore >20 array parsing for req.query repeated keys (8d09bfe6)
    • This also unifies array-cap behavior across notations. Indexed notation (a[0]=...) was historically capped at qs's default arrayLimit of 20 even in older qs versions; after this change it also allows up to 1000 items.
  • deps: qs@~6.15.1
  • deps: body-parser@~1.20.5

New Contributors

Full Changelog: expressjs/express@v4.22.1...v4.22.2

v4.22.1

What's Changed

[!IMPORTANT]
The prior release (4.22.0) included an erroneous breaking change related to the extended query parser. There is no actual security vulnerability associated with this behavior (CVE-2024-51999 has been rejected). The change has been fully reverted in this release.
